I am doing energy simulation for G+4 Labor Accommodation building. In base case, i have considered 2.66 COP. Auto sized as per ASHRAE.

In proposed case, VRF System used with COP of 4.2 with designed capacities. At the end, i am not getting good saving. So please answer for the below.

In the proposed case, the cooling capacities are high. Whether it may be the reason.

If yes. Then what is the solution can be done to get better savings.
